What general characteristic defines asbestos-containing material (ACM)?

Asbestos-containing material (ACM) is defined by its ability to release harmful fibers when disturbed. Asbestos fibers are microscopic and can become airborne when materials containing asbestos are disturbed, damaged, or degraded. When inhaled, these fibers can lead to serious health issues, including lung diseases and cancer.

Understanding this characteristic is crucial for proper handling and management of ACM, particularly in construction and remodeling projects. Proper safety measures, including containment and personal protective equipment, are essential to minimize the risk of exposure during any work involving or around ACM.

While some materials may be deemed stable and pose less risk when undisturbed, it is important to recognize that this condition can change with any form of disturbance, making the potential release of asbestos fibers a critical aspect of handling ACM safely.
